Troopers responded to the single-vehicle accident in the southbound lanes near exit 6B shortly before 5:30 a.m. Sunday. They say the victim is from Cranston and her name is being withheld until her family is notified.
Police say it appears the woman lost control of her SUV, struck the guardrail in the breakdown lane and crashed into trees. She was pronounced dead at the scene.
State police expect to release more details Sunday afternoon.
